Mixing interlaced and progressive clips in the same project
Mixing interlaced and progressive clips in the
same project
When editing on Matrox Axio, you can mix interlaced and progressive clips in
the same project, as long as the clips have the same frame size and frame rate. For
example, when working in a 1080p @ 25 fps or 1080i @ 25 fps project, you can
capture and play back both 1080i and 1080p @ 25 fps clips, although the input
format for capture is set to your project’s video format.
For example, if you capture 1080i @ 25 fps video in a 1080p @ 25 fps project,
the clips will be converted to 1080p @ 25 fps when they are saved to disk.
Therefore, some undesirable results may appear in the clips when effects are
applied to source video that doesn’t match your project’s video format. It’s
recommended that your source video’s scanning mode (interlaced or progressive)
match your project’s video format.
¦NotePanasonic P2 .mxf files and Sony XDCAM EX .mp4 files in
1080p@29.97 fps format are supported in a1080i@29.97 fps project.
The following diagram illustrates a typical workflow for mixing 1080p @ 25 fps
and 1080i @ 25 fps material on Matrox Axio:
